Today's Pure Mobile accessory of the week would make any outdoorsman proud. Basically the Swiss Army Knife of cell phone accessories, PureGear's PX360 ExtremeCase for iPhone 4/4S is more than just an iPhone case, it's also touted as an "extreme protection system."

Voted by Men's Fitness as the "most functional" on their list of "best cases for your iPhone4/4S" the ExtremeCase offers a crazy level of protection, in an ultra-sporty design. There's no risk of your iPhone unexpectedly coming out of the case if it drops; the ExtremeCase is secured by six screws and acts as a 360-degree shield, witha built-in screen protector.

But what makes it really great for the rugged, outdoorsy type or active athlete are additional features, like the built-in loop at the top, which comes with a carbiner, so you can secure your phone when you're on the go or when you've set up camp.

And, aside from the fairly standard kick-stand, PureGear's ExtremeCase offers cool details rarely found in an iPhone case, like a built-in bottle opener and wrench. So even if you're out of service area, your iPhone may just be able to get you out of a sticky situation.
